چکیده

Water dispersible single- and bilayered graphene sheets are produced by a direct exfoliation from graphite flakes in the presence of pyrene-labeled single stranded DNAs, and the immobilized DNA on the graphene surface is further hybridized with a gold nanoparticle labeled complementary DNA to generate gold nanoparticle-graphene nanocomposites.

Surface plasmon resonance of silver and gold nanoparticles in the proximity of graphene studied using the discrete dipole approximation method.

The integration of silver and gold nanoparticles with graphene is frequently sought for the realization of hybrid materials with superior optical, photoelectric and photocatalytic performances. A crucial aspect for these applications is how the surface plasmon resonance of metal nanoparticles is modified after assembly with graphene. Here, we used the discrete dipole approximation method to stu...

The structure and properties of graphene on gold nanoparticles.

Graphene covered metal nanoparticles constitute a novel type of hybrid material, which provides a unique platform to study plasmonic effects, surface-enhanced Raman scattering (SERS), and metal-graphene interactions at the nanoscale. Such a hybrid material is fabricated by transferring graphene grown by chemical vapor deposition onto closely spaced gold nanoparticles produced on a silica wafer....
